Caitlin Sadowski 63fa667c68 Added basic parsing for all remaining attributes, thread safety
analysis. This includes checking that the attributes are applied in the
correct contexts and with the correct number of arguments.

Alexis Hunt aedbfe480f Fix a bunch of HTML compliance problems with LanguageExtensions.html
One weird thing is the addition of several <a name=""> tags where
previously there were id attributes on the <h3> tags. This is because
the id attribute must begin with a letter, not an underscore. The name
attribute is not so constrained, so links will continue to work.

Alexis Hunt c0a2ab6421 Revert "-fexceptions does not, in fact, enable C++ exceptions"
In fact it does. For the driver anyway, and not cc1 which I'm supposed
to pretend doesn't exist.

John McCall 31168b077c Automatic Reference Counting.
Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.

Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

Douglas Gregor 33823727c8 Implement Objective-C Related Result Type semantics.
Related result types apply Cocoa conventions to the type of message
sends and property accesses to Objective-C methods that are known to
always return objects whose type is the same as the type of the
receiving class (or a subclass thereof), such as +alloc and
-init. This tightens up static type safety for Objective-C, so that we
now diagnose mistakes like this:

t.m:4:10: warning: incompatible pointer types initializing 'NSSet *'
with an
      expression of type 'NSArray *' [-Wincompatible-pointer-types]
  NSSet *array = [[NSArray alloc] init];
         ^       ~~~~~~~~~~~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1:
note: 
      instance method 'init' is assumed to return an instance of its
      receiver
      type ('NSArray *')
- (id)init;
^

It also means that we get decent type inference when writing code in
Objective-C++0x:

  auto array = [[NSMutableArray alloc] initWithObjects:@"one",  @"two",nil];
  //    ^ now infers NSMutableArray* rather than id

Douglas Gregor 80af31397a Audit and finish the implementation of C++0x nullptr, fixing two
minor issues along the way:
  - Non-type template parameters of type 'std::nullptr_t' were not
  permitted.
  - We didn't properly introduce built-in operators for nullptr ==,
  !=, <, <=, >=, or > as candidate functions .

To my knowledge, there's only one (minor but annoying) part of nullptr
that hasn't been implemented: catching a thrown 'nullptr' as a pointer
or pointer-to-member, per C++0x [except.handle]p4.

Peter Collingbourne d5d410faa8 Introduce __has_extension macro
__has_extension is a function-like macro which takes the same set
of feature identifiers as __has_feature.  It evaluates to 1 if the
feature is supported by Clang in the current language (either as a
language extension or a standard language feature) or 0 if not.

At the same time, add support for the C1X feature identifiers
c_generic_selections (renamed from generic_selections) and
c_static_assert, and document them.

Patch by myself and Jean-Daniel Dupas.

Douglas Gregor 347d626cf7 Implement CWG1170, which makes access-control errors into template
argument deduction failures. Only implemented in C++0x, since this is
a significant change in behavior from C++98/03.

Sebastian Redl c17003c66b Create __has_feature(cxx_noexcept) and mark it as working.
Find out that our C++0x status has only one field for noexcept expression and specification together, and that it was accidentally already marked as fully implemented.
This completes noexcept specification work.

Jeffrey Yasskin 08a4f8f197 Add an attribute to forbid temporary instances of a type. This allows class
authors to write 

  class __attribute__((forbid_temporaries)) Name { ... };

when they want to force users to name all variables of the type. This protects
people from doing things like creating a scoped_lock that only lives for a
single statement instead of an entire scope.

The warning produced by this attribute can be disabled by
-Wno-forbid-temporaries.
